SUMMARY OF BACKGROUND DATA: The analysis of centre of pressure (COP) excursions
is used as an index of postural stability in standing. Conflicting data have been reported over …

Over the past 20 years, the center of pressure (COP) has been commonly used as an index
of postural stability in standing. While many studies investigated COP excursions in low back …

Study Design. Balance performance in unstable sitting and trunk muscle response to quick
force release were measured in 16 patients with chronic low back pain and 14 matched …

Several recent reviews have reported that 'repetitive movements' constitute a risk factor for
occupational musculoskeletal disorders in the neck, shoulder and arm regions. More …

Low back pain (LBP) is often accompanied by changes in gait, such as a decreased
(preferred) walking velocity. Previous studies have shown that LBP diminishes the normal …

Study Design. Prospective observational study with a 2-to 3-year follow-up. Objectives. To
determine whether delayed muscle reflex response to sudden trunk loading is a result of or …

Objective: To identify differences in postural control among healthy individuals with different
architectural foot types. Design and Setting: We compared postural control during single-leg …

Persons with recurrent low back pain (LBP) have been observed to have altered
proprioceptive postural control. These patients seem to adopt a body and trunk stiffening …

Study Design. Quiet stance on supporting bases with different lengths and with different
visual inputs were tested in 24 study participants with chronic low back pain (LBP) and 24 …

The purpose of this study was to examine whether postural instability observed in persons
with spinal pain and in elderly persons is due to changes in proprioception and postural …
